Title: Process for producing aromatic nitriles and/or alkenyl-substituted aromatic compounds
IPC: C07C5/42
Filed: 1964-08-04
Abstract: Alkenylaromatic hydrocarbons are made by heating at 250-550 DEG  C., a mixture of alkyl-aromatic hydrocarbon and ammonia, in presence of free halogen (except F2) as catalyst.  In examples 6 and 7, styrene and a -methylstyrene are obtained from ethylbenzene and cumene, respectively, at 350 DEG  C., in presence of Al2O3, Br2 and air.ALSO:Aromatic nitriles are made by heating at 250-550 DEG  C., a mixture of alkyl- and/or alkenyl-aromatic compound with NH3, in presence of I2, Br2 or Cl2 (which may be generated in situ) as catalyst.  In examples, benzonitrile is made from toluene, ethylbenzene*, styrene* or cumene (in cases*, benzyl cyanide is also formed), naphthonitriles from methylnaphthalenes, phthalonitriles from xylenes, p-vinylbenzonitrile and terephthalonitrile from p-vinyltoluene, and chlorobenzonitriles from chlorotoluenes.

IPC: G02B17/06
Filed: 1945-11-20
Abstract: 603,126. Optical systems. FARNSWORTH TELEVISION & RADIO CORPORATION. Nov. 20, 1945, No. 31238. Convention date, Aug. 2. [Class 97 (i)] An image-forming system particularly for a telescope or for the projection of television images comprises spherical object and image surfaces and a plurality of members having spherical light-reflecting members all substantially concentric. The mirror 19, Fig. 3, reflects light from an object 16 such as a cathode-ray tube to a convex mirror 17 whence it passes to a screen 24 via mirrors 21, 18 which may, if desired, by omitted. Fig. 4 shows a television apparatus comprising a fluorescent screen 48 adjacent the spherical glass or other transparent surface 53 of a member 52 having a spherical wall 54 and filled with a liquid of the same refractive index as the glass. Light from the screen 48 passes to the concave mirror C and thence to screen 59 via convex mirror 56 and an aperture 58 in the mirror, all the members having the same centre of curvature O. The Specification includes the mathematical analysis of methods of computing the system. The Specification as open to inspection under Sect. 91 describes an alternative, Fig. 5 (Cancelled), in which light from the object 35 passes via mirror B to a refractory member 37, the centre of curvature of the surfaces of which coincide at O with that of the mirror, and thence to the screen 41. Two such refractory members may be used. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for weighing and segregating sliced bacon from a slicing machine
IPC: B26D3/28
Filed: 1974-07-16
Abstract: 1465384 Bacon slicer CASHIN SYSTEMS CORP 16 July 1974 [10 Oct 1973] 31375/74 Heading A4C [Also in Division G3] In a slicing machine and weigher combination, a product e.g. bacon is fed to a slicing blade, the sliced product is weighed and the feed is interrupted when the weight of this product reaches a preset value. The product is then weighed again and any difference from a desired magnitude is used to adjust the pre-set value of the first weighing operation. As shown, bacon 18 is fed by hydraulic piston 20 to blade 22, and then to a conveyer 40. The feed is stopped when scale 42 associated with conveyer 40 registers a pre-set weight on the conveyer. An error in weighing may occur e.g. due to vibrations caused by feeding bacon on to the conveyer 40, so the slices of bacon are transferred to a second check weigher 34. If the second weighing differs from a desired range, the pre-set value of scale 42 is adjusted by servomotor 56 in proportion to the difference. In an alternative only a single weigher is used and the second weighing operation is carried out by scale 42 a suitable time after the first weighing.

Abstract: 1,242,055. Pneumatic separation. FAWKHAM DEVELOPMENTS Ltd. 6 Sept., 1968 [12 July, 1967], No. 32132/67. Heading B2H. [Also in Division F4] An apparatus for fluidizing aggregate material having a surface moisture content, e.g. small coals, quarried stones or mineral ores, in order to separate dust and small granular particles therefrom, comprises a fluidizing chamber 2, Fig. I, having means, e.g. perforations 4, in its bottom wall for the introduction of fluidizing air so as to create a fluidized bed 12 of material in the lower part of the chamber, the air being at a temperature insufficient to separate the dust and small granular particles, and means, e.g. jets 14, for introducing heated air into the chamber above the bed 12 so as to maintain such temperature and humidity above the bed as to separate and dry the dust and small granular particles. The fluidizing air, which may be at or above ambient temperature or which may be saturated at the temperature of the bed by the addition of steam or the recirculation of part of the air leaving the apparatus, is introduced via an inlet 9 and a wind box 3 through the perforated wall 4. The material is fed down a chute 5, the coarse material being discharged at 6 and the dust and small particles at 7 to a duct 8 connected to a cyclone, baffle chamber, filter or scrubber. The jets 14 are provided in one or more walls of the apparatus and direct the air either horizontally or downwardly towards the upper surface of the fluidized bed 12. Agitators 10 assist in maintaining the bed in its fluidized state. In a modification, Fig. 3 (not shown), instead of a perforated bottom wall 4 and agitators 10, spaced apart elliptical rods (15), alternate ones of which have their major axes at right angles, are provided at the bottom of the chamber 2 and are rotatable in the same direction and at the same speed. In a further modification, the hot air jets 14 are omitted and heated air is introduced into the chamber 2 together with the aggregate material either directly into the chute 5 or, as shown in Fig. 2, through an inlet 18 in a subsidiary wind box 17 formed below slats or louvres 16 which constitute the floor of a modified chute 5.
